Feedback: change interface to configuration basePath property

Rather than having a client pass use the URL to the API (or environment) they want to use, what if we exposed a `production` key in the `Configuration` which switch between int and prod:

```js
// This
const apiConfig = new Configuration({
  production: false
})

// Instead of this:
const apiConfig = new Configuration({
  basePath: "https://int-api.mx.com",
})
```
